Wasn't the whole argument for jumping that it allows for more options? I don't see why a toggle that in no way effects jumpers themselves would be such a bad thing. It shouldn't be that hard to add either, considering that it's only an animation and your actual hitbox is still on the ground (if the no function interview is to be believed).

You get arguments that tell us to just deal with it, but why? For an attention hogging animation with no practical use, a toggle would be a fine option to those of us that don't want to see it without bothering the experience of those that do.
